7.5. Motion of machine on the nozzle buffing check
7 working lines execute the nozzle buffing check.
(1) Measurement of vacuum release
By comparing vacuum release level (2) with vacuum sealing level (6), it is judged whether
buffing adheres (7).
1. XY-axis moves to [Brow STN position X], [Brow STN position Y].
2. Z-axis moves of head to [Brow STN height (mm)] + [Height change speed (mm)] at
speed of 100%.
3. Vacuum ON of head waits by [Vacuum timer (msec)].
4. Measurement of vacuum release.
(2) Measurement of grounding vacuum level before a buffing.
The vacuum level for judging whether buffing adheres by (7) is measured.
1. Z-axis moves [Brow STN height (mm)] + [Grounding height (mm)] of head by speed
[Grounding down speed (%)] %.
2. Vacuum ON of head waits by [Vacuum timer (msec)].
3. Measurement of grounding vacuum level before a buffing.
(3) Press-in by servo buffing.
The Z-axis is moved to the coordinates for performing a load check.
1. Z-axis moves [Brow STN Height (mm)] + [Buffing check approach stroke (mm)] of head
by speed 100%.
2. Servo buffing Z-axis moves [Load of harden check (N)] to [Measurement Height (mm)] +
[Buffing check approach stroke (mm)] + [Buffing stroke (mm)] head by speed [Slide
down speed (%)]
